I had a harken 8:1 mainsheet blow up during Tybee, Harken replaced the lower block assembly for free, no questions asked.

I also blew up some ronstan blocks trying to run a 2:1 system on the spinnaker, they weren't auto ratcheting or anything special but simply weren't built to the same toughness of a comparable Harken block (no Harkens in stock at WM).

I've used the harken setup on the N20's and its worked perfectly fine, seems fairly bulletproof. As a tip, its best to at least spray the auto ratchet blocks after sailing in salt water, better to soak them overnight in a bucket of soapy water
